A few years ago, I was just like you — confused, curious, and a little overwhelmed.
I had just discovered bug bounty programs. I read stories of people earning money by finding bugs in websites and apps. It sounded exciting — and honestly, like a dream job.
But the more I read, the more terms I saw that made no sense to me.
Web2? Web3? Smart contracts? IDOR? What was I even supposed to learn first?
So let me take you through the same path I followed — with zero jargon, and everything explained simply.
Let’s imagine the internet as two different neighborhoods.
🏘 Web2 — The Familiar Streets
This is where you live right now.
You log in to Instagram, order food from Zomato, check your college portal, or browse Amazon.
These websites and apps are Web2 platforms.
They have login forms, user profiles, admin dashboards, and lots of moving parts behind the scenes. Most companies run their businesses here.
